SNARE-CURETTE.

To all whom 'it may concern:

Be it known that I, FRANK B. BLACK, a citizen of the United States, residing at Gilboa, in the county of Putnam and State of Chio, have invented certain new and useful Improvements in Snare-Curettes, of which the following is a specification.

This invention relates to certain new and useful improvements in surgical instruments, and comprises a snare curette.

The object of my invention is to provide a light, simply constructed and readily operative ecraseur, offering elective adjustments' to the snares, so that they may be brought below, above or to the side of the offending mass.

Vith these and other objects in view, the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described and particularly pointed out in the appended claims, it being understood that changes in the specific structure shown and described may be made within the scope of the claims without departing from the spirit of the invention.

In the drawings forming a part of this specilication, and in which like numerals of reference indicate similar parts in the several views z-Figure l shows a front View disclosing the curette in a closed posit-ion, Fig'. 2 shows a front view disclosing the snares as opened, Fig. 8 is a closed edge view, Fig. 4t is a face view disclosing the curette as unfolded, Fig. 5 discloses an outlined view showing the instrument inserted into the womb and under the oiending mass, Fig'. 6 discloses the plunger pushed up and shows the snares as open, Fig. 7 shows the snares turned up over the offending mass and ready to be loosened, Fig. S discloses the snare as compressing the offending mass, Fig. 9 is a lower end view of the instrument as unfolded.

This invention relates to that class of surgical instruments, which are used for scooping or scraping away or otherwise removing substances, such as granulatlons, cysts, or small polypi, from the cavity of the uterus.

My invention comprises two similar bars 5 and 6, which are rectangular in cross sec-v tion, each terminating at one end in a curved finger hold 7. The opposite end of each bar is slotted and perforated as shown at 8 to provide two securing ears. One of these Specification o Letters Patent.

bars or members as the one marked 6 is provided along one edge with the serrations 10. These members 5 and 6 are hingedly connected at their upper ends by means of a hinge 11 while at their lower ends the two members are hingedly connected by means of the hinge 12. Slidably held upon each of these bars 5 and 6, is a sleeve 13, these sleeves also being hingedly connected by means of the hinge ears 14. As shown, each one of these sleeves 13 is provided with a notch 15, and secured within ythese notches 15 at one end and the slots S at the other, are the two similar snares 16, which have their ends recurved in opposite directions and arranged to be held within the slot and notch as shown. 'Ihese snares are in the form of flat sharp edged spring members which are normally perfectly straightas disclosed. The normal position of the sleeve 13 is determined by these springs, which lie perfectly fiat against the connected bars. As constructed, the lower entering end of the instrument presents a smooth and rounded surface. Secured to the sleeve 13, mounted upon the bar 6 having the serrated edge 10 is a plunger rod 17, which is of such a tl1iclr ness that when the instrument is in its folded position, as shown in Fig. 1, this plunger' is squarely held between the two members. rIhis plunger is provided with the curved thumb hold 18 while intermediately of its ends it is provided with the collar 19 adapted to be brought into the serrations 10 in adjustably securing this plunger. As these bars 5 and 6 are hingedly connected, each snare can be carried in an arc of ninety degrees.

The operative positions of the instrument in use are clearly disclosed in Figs. 5, 6, 7, and 8. In Fig. 5, the curette is positioned below the offending mass the snares being in their normal position. In Fig. 6, the plunger has been advanced so as to open the snares with the snares in opposite directions below the offending matter. In Fig. 7 the instrument has been turned to bring the snares in juXta-position, while in Fig. 8, the plunger has been drawn outward so that the snares have been clasped upon the offending matter.

rlhe device is light, neat, and simple in construction. When the blades or snares have been compressed upon the offending matter, the mass is reduced in size and so Patented Aug. 24, 1909.

may be more easily removed. The snares when opened, or in their closed position may be held at any desired angle, and may be carried up and around any substance that happens to be in the path of the snares. By releasing the plunger and making traction on the plunger, the mass may be securely held.

And having thus described my said invention, what I claim as new, and desire to secure by United States Letters Patent is l. A snare curette, comprising two similar members hingedly connected, a plunger secured between said two members, a snare secured to each of said members, and means to connectthe snares to said plunger. i

2. A snare curette comprising two similar members hingedly connected at their upper and lower ends, a sleeve carried by each of said members, a snare secured to the lower end of each of said members, and at their upper ends to one of said sleeves, and a plunger carried by one of said sleeves.

3. A snare curette comprising two similar members hingedly connected, one of said members having a serrated edge, a sleeve carried by each of said members, a snare in the form of a flatspring secured to the lower end of each of said members, said snares at their upper ends being secured to said sleeves, a plunger secured to one of said sleeves, and a collar carried by said plunger adapted to engage the serrated edge of said member.

4. A snare curette comprising the combination of two similar members, a hinge connecting said members, one of said members having a notched edge, a sleeve carried by each of said members, a hinge connecting said sleeves, a snare in the form of a flat spring secured at its lower end to the lower end of each of said members, the upper end of each snare being secured to one of said sleeves, a plunger secured to one of said sleeves, and a collar carried by said plunger adapted to engage the notched edge of said member.

5. The combination in a curette, of two bar members hingedly connected along one edge, and a plunger slidably carried by one of said members.

(3. A snare curette comprising two similar members pivotally connected, a plunger secured. therebetween, a snare connected to adjacent ends of each of the members and slidable connections between the plunger and the snares.

ln testimony whereof I afIiX my signature, in presence of two witnesses.
